HOISTING=MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,621, dated February12, 1889.

Application filed May 8, 1888. Serial No. 273,180. (No model.)

To all whom it may concern.-

Be it known that I, Gnonen JAY ANDER- SON, of Test Superior, in thecounty of Douglas and State of Viscousin, have invented a n ew andImproved Ho isting-Machine, of which the following is a full, clear, andexact description. 7

The object of the invention is to provide a new and improvedhoisting-machine, specially adapt-ed for loading and unloading vessels,cars, &c.

The invention consists of certain parts and details and combinations ofthe same, as will be described hereinafter, and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts broken out.Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged endelevation of part of the improvement. Fig. at an enlarged sectional sideelevation of the carrier and tripping device; and Fig. 5

is a plan view of the carrier.

The improved hoistin g-maehine is provided with a mast consistingprincipally of a vertical frame, B, provided on its bottom with a pin,B, mounted to turn in a bearing,

formed on the platform 0. On the upper end 'of the frame B,in itsmiddle, is held a pin, B

mounted to turn in a suitable bearing formed in the ends of the beams Dof a suitable frame, D, erected on the platform 0, next to the up rightframe B.

From the bottom of the frame B project outward and upward the beams B,which, in connection with the beams B, secured to the top of the frameB, support the boom E, made of two parallel beams, E and E connectedatthe top and bottom by cross-pieces E said beams E and E thereby forminga track on which travels the carrier or carriage F, provided with theusual wheels, F, supporting a frame, F in the middle of which is mountedto rotate a pulley, F over which passes the hoisting-rope G, secured byone end to a trans verse bar, F", held 011 the frame F of the carrier F.

The beams B are united at their outer ends,

which are connected by a link, B with the pin B and from the said endsof the beams B extend the braces B, supporting the lower part of theboom E. From the upper part of the frame B extend the braces B whichassist in supporting the upper part of the said boom E, which is thusheld on the mast in such a manner that the weight concentrates in thelower part of the frame B, and the latter is thereby easily turned onits pivotsthe pins B and B The hoisting-rope G supports thehoistingbucket H by passing under a pulley, H, mounted to rotate in aframe, H carrying at its lower end a hook, H supporting a bail, H, pivotally connected at its ends to the sides of the bucket H said bucket11 being limited in its swinging movement by the stops H and H againstwhich said bail H rests alternately, the stops H and H being secured tothe outer portions of the sides of the bucket H, as is plainly shown inFigs. 1. and 4;.

On the middle part of the bail H is hinged an inclined rod, H providedon its outer end with a notch, H adapted to engage a projection, Hsecured on the rear wall of the bucket H Said rod H when engaging saidprojection H holds the bucket H in a vertical position, so that thebucketsupports the load to be carried. Said rod H is to be disengagedfrom the projection H byatripping device, 1, consisting principally of aL} shaped lever, l, fulcrumed at I to the outer sides of the beams E andE" of the boom E, as illus' tratedin Figs. 1 and 4. The lover I isprovided at each end with an upwardly-extending projection, 1 connectedwith one end of a spring, I, secured by its other end to the side of therespective beam E or The outer end of the said projection I is alsopivotally connected by a link, 1 with a bloek,l, held to slide on top ofthe respective beams E and E of the boom E, the said blocks 1 beingconnected with each other by a crosspiece, 1 and the said blocks 'areadapted to be engaged by the wheels F of the carrier F in order tooperate the tripping device I. The hoisting-rope G also passes over apulley, J, mounted to rotate in a block, .1", pivotally c011- nectedwiththe upper end of the boom E. The rope then passes from this pulley.T to

, pin N and the pulley N a sheave, J supported from a transverse beam, Dof the frame D. 'lhehoisting-rope G then extends downward and isconnected with a Windlass, K, of any approved construction, and locatedon the platform ()neend of the block J carrying the pulley J isconnected with one end of a rope, L, extending rearward and passing overa sheave, L, supported on a post of the frame I), and the said rope Lthen extends downward and is secured by its lower end to a cleat, Lsecured. to the lower end of the said post of the frame 1).

To the front axle of the carrier 1 is connected one end of a .rope, N,extending upward and passing between pins .1 held in the' block J, andthen passing on farther upward and over a pulley, if", mounted on atransverse beam, D, of the frame D, and then the said rope extends alongthe said beam D and passes over a pulley, Y and then under a pulley, lsupporting a weight, N, and then the said rope N extends upward and issecured by its end to a cleat or pin, N, secu red on the said beam 1)".

In the frame D is formed a hopper, 0, provided on its lower end with aspout or chute, O, which is adapted to be connected with cars or otherreceptacles to be loaded. On the front 'end of the hopper O is pivoted atransverse extension-plate, adapted to close the upper front end of thesaid hopper whenever desired.

7 The operation in as follows: The platform (J usually forms part of adock, and on the said platform is mounted to swing the mast, so that thelower end of the boom E can be brought over a vessel to be unloaded. Themast, with its boom E, is turned on the pivots B and B by pulling on therope L or G until the lower end of the boom E is in the desiredposition, so that the hoisting-bucket H is directly over the hatch ofthe vessel to be loaded. The rope L is then fastened by its lower end onthe cleat L and then the windlass K is operated, so as to unwind thehoisting-rope G, whereby the carrier F by its own weight travelsdownward on the beam E until the hoisting-lmeket H is directly over thehatch of the vessel. This downward movement of the carriage F causes adownward movement of the rope D, and when the desired position of thesaid hoisting-bucket over the hatch is reached then the operator fastensthe end of the rope X to the pin or cleat in such a manner that thepulley N is in its uppcrn'lost positionthat is, between the The rope Nwill now prevent a further downward movement of a carrier F at alltimes, and when the operator now continues to unwindthe rope G from thehoisting apparatus K the said rope G will cause the bucket ll to passdown the hatch into the hold of the vessel. The bucket is then loaded inthe usual manner and the rod H holds it in a vertical position byengaging by its notch l-I the projection I1 hen the bucket is filled,the hoisting apparatus K is again set in motion, so as to wind up therope G, whereljiy the hoisting-bucket H is lifted out of the holdthrough the hatch until the pulley ll comes in contact with the pulley lof the carrier I A further winding up of the rope (i now causes anupward traveling movement of the carrier F with the hoisting-lnieket H.()n the upward movement of the carrier h its front wheels, F, come incontact with the blocks l, which are then moved forward and cause anupward swinging movement of the lower part of the lever I by beingconnected with the latter by the links The middle part of the U-shapcdlever I is thus thrown against the bottom edge I of the rod if, so thatthe latter is swung upward and out'of contact with the projection H Thebucket, on account of being heatier at its front end than at itsreaigtilt-s over, turning at the pivot-points the lower end of. the bailll' As the bucket ll. at this time is directly over the hopper O, thecontents of the bucket H are thrown into the said hopper 0, after whichthe bucket H rights itself and the notch H of the rod H again engagesthe projection H \Vhen the bucket is loaded, its forward or inclinedhalf is the heavier, and therefore as soon as the latch is released thebucket dumps; but when empty the rear half of the bucket is the heavier,an (1 hence the bucket will right itself, as stated, as soon as dumped.Vhen the carrierF travels upward, as before described, the weight Ncauses the pulley N to exert a pressure on the rope N, so that all slackof the latter is constantly taken up. Now, the operator again causes thehoisting apparatus K to unwind the h oisting-rope G, an d the carrier F,with the hoisting-bucket H, travels downward until the pulley N carryingI the weight N", is again in its uppermost position, as beforedescribed, and the said carrier F is then held in a fixed positiondirectly over the hatch of the vessel to be unloaded. The above-described operation is repeated. "When the carrier F moves downward from itsup permost position, the sprin I move the lever I and the blocks 1" backto their former positions, so as to be ready to engage the rod I lagain, as before described. I Thus it will be seen that the entiremachine is easily operated and the boom on be swung to any desiredposition and held there, so that the hoistiug-bucket is always over thehatch of the vessel and connects at its upper end with the hopper O, thelatter being sufficiently wide to pcrmitthe bucket H to unload when inan angular position, as shown in dotted lines in Fig. 2.

It will further be seen that the entire device is very simple anddurable in construction and very effective in operation.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the frame D, having a hopper, O, of thevertical mast journaled in said frame in front of the hopper, and having an inclined boom, E, extending rearwardly beyond the mast into theframe over the hopper, and a carriage traveling on the boom past themast, substantially as set forth.

The combination, with the sup1 )ortingframe, and the vertical mastadapted to rotate and having an inclined track-boom extending in. rearof the mast at its upper end, and provided with a trip at said rear end,of a carriage tray'eling on the boom and carrying a dumping-bucketprovided with a latch into the path of which said trip projects,substantially as set forth.

3. The combination, with the frame having forwardly-proj ecting topbeams, D, and a forwardly-proj ecting base, (7, of the Vertical mastjournaled in the said projecting parts of the beams and base, and havingan inclined boom proj eeting at its rear or upper end beyond the mast,the carriage traveling 011 the boom, the rope N, passing over pulleys onthe frame secured at its ends to the frame and having a weighted pulley,N", suspended from it, the

hoisting-nope G, secured to the carriage and having a traveling pulley,H, under the carriage, passing thence over a pulley onthe carriage to apulley on the frame, and the rope L, for turning the boom, substantiallyas set forth.

4:. The combination, with theinclined boom and the carriage travel i nthereon, of the tripping-lever l, pivoted at the upper end of the boomprojecting forwardly thereunder, pro vided at its ends withupwardly-extending projections I", springs I", connected to the boom andsaid 'n'ojeotions, links I, extending rear- \vard'l y from said projecti ons, and the blocks 1, sliding on the boom in the path of thecarriage and connected to said projection, where by when the carriageforces the blocks rearwardly the lover I will be operated, substantiallyas set forth.
